PUMP.

$PECIPICATION forming part of Letters Patent No. 363.677, dated May 24, 1887.

Application filed January 5, 1887. Serial No. 23,472. (No model.)

To all whom it may concern:

Be it known that I, J osnrn RAAB, of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Lift and Force Pumps; and I do hereby declare that the following is a full, clear,'and exact description of the invention, which will enable others skilled int-he art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to force-pumps, and has for its object to produce a pump that shall be simple and durable in construction and not likely to get out of repair. The pump, being submerged in a well or located in any desired place, will, as the crankhandle is rotated, force a stream or streams of water or elevate it or them to a tank, or be utilized for sprinkling, extinguishing fires, or any such like purposes.

Vith these ends in view my invention consists in the combination and construction of parts, hereinafter fully described, and then specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of the pump complete. Fig. 2 is a plan view with the piston-head removed. Fig. Bis a section on the lineg y, Fig. 1, showing one piston raised on the platform and the others down on the bottom. Fig. 4 is a plan view of the piston-head removed .from the casing or pump. Fig. 5 is a side elevation of the same with one piston up and the others down. Fig. 6 is a sectional perspective View showing the guideways to elevate the pistons to the platform. Fig. 7 is a sectional detail showing the guideways. Fig. Sis a plan view showing a modified form of the piston-head. Fig. 9 is a detail of the piston of same.

Similar letters indicate like parts in all th figures.

A is the casing or pump proper, having a removable top, A, through which passes the shaft B. This shaft also passes through the piston-head O and projects a short distance beyond the head, in order to give it a proper bearing in the step d of the elevated platform D. This platformDsupports the piston-head (J, and is made sufficiently high from the botguideways E, and fall on the opposite side of the platform D. This central guideway is preferably made of a piece of metal (bent in the form shown in Figs. 2, 6, and 7) and Se cured to the top of the platform D, as at e, by soldering or in any suitable manner. It then curves downward and outward from the platform D until it gradually leaves off in the bottom, as shown at e in Fig. 7.

Opposite the central guideway formed by a projection from the casing or pump is another guideway E, which is curved as the central guideway, and also assists in the elevation of the pistons F. The central guideway E is directly in the center of the passage of the pistons F, so that as the pistons pass around they will travel up the said guideway E, ride over the platform D, and fall upon reaching the side opposite said guideway E, where they proceed on around in their course, passing up and over the guideways and platform as the piston-head O is rotated, as will be hereinafter more fully described.

G is the inlet; G, a wire screen, which keeps out all dirt and foreign matter. The water flowing in through the opening is taken around by the pistons F as they make a circuit of the pump, and forced out through the outlet G. The outlet is arranged so that a hose or pipe may be attached to convey the water to any desired place.

Near the top of the casing, and above the piston-head, is placed an outlet, K, which may be used the same as outlet G. As the piston head O is in operation considerable water passes through the slots 0, and by having an outlet above them I am enabled to force two streams at the same time. When it is desired, either outlet may be closed. The upper outlet, being of smaller dimensions and not being supplied with the same volume of water, will give the lesser stream.

Between the inlet and outlet, and directly under the platform D, there is a partition, (I, forming a wall, which divides these two points, as will be seen in Fig. 7. This partition extends from the rounded portion of the platform D to the wall of the casing A. The piston ICO the wall of the piston-slide, is secured, inza small lug, c, a wire spring, which extends from the lugs 0 through small holes 0 in the pistons F, and adapted. to force the pistons down as they pass up and over the platform I). Extending through the piston-head G-is the shaft B, which is rigidly secured to said head. This shaft extends slightly beyond the bottom of the piston-head and restsin the step d in the rounded portion of the platform D. I have shown in Figs. 8 and 9 a modified form of piston-head.

The piston h ead is made substantially as that before described, but with this exception, that in the heads I form the semicircular slots H, terminating in the radial slots 6. At the rear end of the slots H, I form ears or lugs Hi, the purpose of which is to receive the projections It h, formed on the curved portion of the piston-head, whereby the same is pivotally secured, thereby allowing the pistons to rise and fall, or have a vertical movement in the radial slots 6, and it will then be seen that when the piston-head is rotated the pistons will travel up the guideways E and over the platform D, and fall, in the manner before described.

The entire pump is placed together and operated in the following manner: The pistonhead 0 is placed in the casing (or pump proper) A, resting on the elevated platform I), the eX- tended portion of shaft B resting in the step d. The top or cover A is then placed over the shaft B, said top having on its inner side a hub, A, which rests on the top of the pistonhead 0. The top'or cover A is then secured firmly to the casing A. The piston-head O is held securely from any vertical movement. The shaft B extends the desired distance upward and has on its end the crank I. The pump may be submerged in water or located in any desired place. The water flowing in through inlet G, the shaft B is then rotated, which will cause the pistonhead O to revolve. The pistons F will pass along the bottom until they reach the inclined guideways E, up which they travel to the platform D, over said platform, falling on the opposite side in front of the inlet G, where they will force the water around I am aware of the following patents: To

Houghton, No. 153,566, which shows a cylinder arranged horizontally and in which is a revolving disk, and divided centrally and having means to draw water, and ejecting the same by blades fitted in longitudinal slots,and adapted to slide laterally in saidslots,provided with cams to pass the cut-offs. The patent to Le Blair, No. 155,455, which simply shows a series of buckets moving about a circular channel, below a horizontal wheel which moves them, the channel at one side descending to a cavity, into which the water flows. Said buckets are contrived so as to be raised off the bottom of the channel after passing an exit, and then lodged on a wheel, which carries said buckets until they return to the point wherethey take water again, when they are tripped and fall again to the bottom of the channel. Patent No. 224,331, to J. F. Gelletly, shows a cylinder having acam-race. A shaftpasses through the cylinder and is secured to a disk adapted to be revolved. Stuffing-boxes are placed on a disk, through which pass rods carrying pistons, and their upper ends are secured to disks adapted to engage with a cam-race. Patent to Upham, No. 160,974, shows simply a horizontal cylinder in which are pistons adapted to fall into and out of slots formed in aceutral portion. I therefore do not desire to claim, broadly, any of the means above described, and

\Vhat I do claim, and desire to secure by Letters Patent, is-

In a cylindrical force-pump having a re movable cover, a base havinga platform thereon, and inclined guideways, a piston head supported on said platform and provided with radial slots adapted to receive pistons having vertical movement therein, and having their upper portion secured to springs and adapted to travel up said guideways, and means for rotating said piston-head, inlet G, and covering G, and outlets G and K, all substantially as set forth, and for the purposes described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
